Fill out Form I-9 on your phone
Every employee hired in the United States completes Section 1 of Form I-9, and the employer completes Section 2 after examining the employee's identity and work-authorization documents. The form stays with the employer; it is not filed with USCIS. This page covers the employee's part and how to do it neatly on a phone.

What the I-9 is for, and who fills it in
What it is for. It records that the employer verified the employee's identity and authorization to work in the United States, as federal law requires for every new hire.
Who fills it in. The employee completes and signs Section 1 no later than the first day of work for pay. The employer (or an authorized representative) completes Section 2 within three business days of the start date after physically examining the documents, or using the alternative remote procedure if the employer is enrolled in E-Verify. Someone who helps the employee fill in Section 1 completes Supplement A.
Where it goes. To the employer, who keeps it for three years after hire or one year after employment ends, whichever is later, and produces it for inspection on request.
The fields that matter
| Field | What to enter |
|---|---|
| Section 1, Name and address | Last name, first name, middle initial, any other last names used (such as a maiden name), current address, date of birth. |
| Social Security number | Optional for the employee unless the employer uses E-Verify, in which case it is required. |
| Email and phone | Optional. Employers enrolled in E-Verify may use the email to notify you of a mismatch. |
| Citizenship or immigration status | Check exactly one of the four boxes: U.S. citizen; noncitizen national; lawful permanent resident (enter your USCIS or A-Number); or noncitizen authorized to work (enter the expiration date if any, plus one of USCIS A-Number, Form I-94 admission number, or foreign passport number and country). |
| Signature and date | Sign and date Section 1. You attest under penalty of perjury that the status you checked is true. |
| Documents (not a field) | You will show the employer either one List A document (such as a U.S. passport or Permanent Resident Card) or one List B identity document (such as a driver's license) plus one List C work-authorization document (such as a Social Security card without restrictions or a birth certificate). The lists are the last page of the PDF. |
How to fill out the I-9 in FormFill
- Get the official PDF onto your phone. Tap the agency link above and save the PDF (on iPhone, Share, then Save to Files; on Android it lands in Downloads). Only use the agency's own copy: the form changes, and an old revision can be rejected.
- Import it into FormFill. Open FormFill and tap Import PDF, then pick the file. FormFill writes on top of the page, so it does not matter whether the PDF has fillable fields or is a flat scan.
- Fill the fields. Tap Text, then tap where an answer belongs and type it. Drag to move, pull a corner to resize. Use Check for the checkboxes and Date where a date is asked for. Pinch to zoom on the small boxes.
- Sign it. Tap Sign to draw your signature (or reuse a saved one with Pro) and place it on the signature line, not on the printed-name line. Initials covers any initial boxes.
- Finish and send. Tap Done. FormFill flattens your entries into the PDF and offers Share a copy or Save to device. Open the exported file once before you send it.
On this form: Fill only Section 1. Use Check in one citizenship box, type any A-Number or I-94 number into the matching line, and leave Section 2, Supplement B and the employer blocks untouched: your employer completes those. If a preparer or translator helped you, they complete Supplement A themselves.
Mistakes to avoid
- Section 1 is due by your first day of work; do not wait for the employer to ask.
- Check one status box only. Two boxes, or a box with no supporting number where one is required, makes the form incomplete.
- Use the current edition of the form; the edition date and expiration are printed at the bottom of each page, and USCIS's I-9 page says which editions are valid.
- Your employer decides how your I-9 is stored. A PDF you completed in FormFill can be printed and signed on paper if they require a wet signature, or retained electronically if their system meets the federal rules for electronic I-9s.
- Bring original documents. Photocopies are not acceptable for Section 2 (a certified copy of a birth certificate is the exception).

Questions people ask
Do I send Form I-9 to USCIS?
No. The completed form stays with your employer. It is never filed with USCIS or any other agency unless an inspector requests it.
Can I complete Section 1 of the I-9 on my phone?
Yes. Section 1 is the employee's part, and typing it on the official PDF produces a clean, legible form. Your employer then completes Section 2 after seeing your documents. Ask whether they want the file or a printed copy.
Which documents do I need for the I-9?
One document from List A, or one from List B and one from List C. The Lists of Acceptable Documents are the last page of the official PDF. You choose which acceptable documents to present; the employer may not tell you which ones to bring.
What if I'm not a U.S. citizen?
Check the box that matches your status: noncitizen national, lawful permanent resident, or noncitizen authorized to work, and enter the number the form asks for beside it. If your work authorization has an expiration date, enter it; your employer must reverify before it expires.
